APC Battery Alarm not Blinking when battery about to die

[bhamraelectric]

Hello there,

I have a Tsugami Swiss Lathe with Fanuc 16iTB control

The APC blinking message not shown on the screen when battery is about to die.
After the battery died, It shows APC alarm and reference positions lost.

Is there any parameter I have to change for the pre-warnings of APC 'APC Blinking' (battery Low).

I have another problem with the Machine

FAN Alarm regular blinks on the screen with black color, the machine runs fine while it blinks. File attached.

I want to remove this blinking fan alarm.

I know nothing about your machine, but... If the 'FAN' alarm is for a cooling fan, is it possible that the shutdown is due to overheating and not a dead battery?
